[TYPO3-install] Upgrade 4.3->4.5 renders backend inaccessible

[Ki-Hyoun Kim]

If you cant access the backend now, first edit the localconf.php,
$TYPO3_CONF_VARS['EXT']['extList']:

It should look like this:
$TYPO3_CONF_VARS['EXT']['extList'] =
'tsconfig_help,context_help,extra_page_cm_options,impexp,sys_note,tstemplate,tstemplate_ceditor,tstemplate_info,tstemplate_objbrowser,tstemplate_analyzer,func_wizards,wizard_crpages,wizard_sortpages,lowlevel,install,belog,beuser,aboutmodules,setup,taskcenter,info_pagetsconfig,viewpage,rtehtmlarea,css_styled_content,t3skin';

Remove the Entry "js_css_optimizer" in the ExtList List by Hand. Then
delete all the "temp_*" files in the typo3conf directory. Now you
should be able to login to the backend again.

Greetings and a Happy New Year!!
